DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic half-cut tree used as a planter, a retaining wall, a pond landscape material in a park, an amusement park, a promenade, and the like. The present invention relates to a structure of a plastic half-cut tree which can be easily connected to each other using the half-tree.

[0002]

2. Description of the Related Art A half-cut continuous tree has a shape in which a plurality of timbers are juxtaposed in a row as viewed from the front side, and is suitably used as a planter for a park or the like, as a soil retaining material, or as a landscape material for a pond. A conventional half-cut tree is made of concrete, has a large weight, and has difficulty in carrying and handling. In addition, when constructing a concrete half-cut tree,
The back surface must be fixed in the soil for each block, and the operation is complicated.

[0003] Recently, artificial wood made of plastic has been developed, and plastic half-trees have also been developed.

[0004]

However, a conventional plastic half-cut tree requires a connecting tool different from the half-cut tree in order to connect the half-cut trees (for example, Japanese Patent Publication No. No. 37775). It is also conceivable to integrally form a connecting rod for connecting the half-slice trees to the back of the half-slice tree.In this case, however, the connecting rods interfere with each other between the adjacent half-slice trees. In such a half-tree, it is necessary to arrange a half-tree in which the position of the connecting rod is offset. For this reason, two types of dies are required as dies for forming a half-cut tree in which the connecting rod is integrally formed by injection molding or the like, and two types of half-cut columns in which the forming positions of the connecting rods are offset. Wood had to be molded. This not only increases the production cost of the half-cut tree, but also has the trouble of transporting two types of half-cut tree to the construction site of the half-cut tree and arranging them alternately.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a plastic half-cut tree that can be easily connected to each other using a single type of half-tree. I do.

[0006]

According to a first aspect of the present invention, there is provided a plastic half-brushed tree having a shape in which a plurality of timbers are juxtaposed and connected when viewed from the front side. A plastic half-cut tree, a first connecting rod provided on the rear side of the plastic half-tree so as to protrude from both ends of the half-tree, and a back of the plastic half-tree. A second connecting rod provided so as to protrude from both ends of the half-connected tree, and a distance from a lower surface of the first connecting rod to a first vertical end of the half-connected tree. Is (H1), and H2 = H1 + α (where α is 0 or more), where (H2) is the distance from the lower surface of the second connecting rod to the second vertical end of the half-connected tree. It is characterized by the following.

[0007] In the half-jointed tree according to the first aspect of the present invention, it is preferable that the first connecting rod and the second connecting rod are integrally formed on the back surface of the plastic half-cut tree. Further, these connecting rods are preferably formed continuously in the horizontal direction, but may be formed intermittently without necessarily being formed continuously.

[0008] A plastic half-cut tree according to a second aspect of the present invention is a plastic half-cut tree having a shape in which a plurality of woods are juxtaposed and connected when viewed from the front side. On the back side of the tree, there is a connecting rod provided so as to protrude from both side ends of the half-slice tree, and a first vertical direction of the half-slice tree from a lower surface of one first end of the connection rod. The distance to the end is (H3),
From the upper surface of the other second end, the first in the vertical direction
When the distance to the end is (H4), H4 = H3 +
α (where α is 0 or more).

[0009] It is preferable that two or more connecting rods are integrally formed on the back surface of the plastic half-cut tree according to the second aspect of the present invention. Further, it is preferable that these connecting rods are formed continuously in the horizontal direction, respectively.
It is also possible to perform intermittent molding without necessarily performing continuous molding.

[0010]

In the plastic half-length tree according to the first aspect of the present invention, since H2 = H1 + α (α is 0 or more), when connecting these half-length trees in the horizontal direction, they are connected. The upper and lower half-trees to be connected are arranged upside down with the upper and lower half-series trees to be connected. As a result, the first connecting rod and the second connecting rod to be connected to each other are arranged offset without interference between adjacent half-cut pseudo trees, and these can be easily connected. By repeating such a connection, it is possible to alternately arrange and connect one type of half-cut pseudo tree while turning it upside down, and see from the front side that many pseudo trees are arranged side by side in order. appear.

In the plastic half-cut tree according to the second aspect of the present invention, H4 = H3 + α (where α is 0 or more)
Therefore, when these half-cut serial trees are connected in the horizontal direction, the upper and lower half-cut serial trees to be connected are arranged without being reversed from the upper and lower sides of the other half-cut serial tree to be connected. As a result, the connecting rods of the two half-connected trees are
They are arranged offset without interference between adjacent half-cut pseudo trees, and these can be easily connected. By repeating such connection, it is possible to arrange and connect one type of half-cut pseudo tree without turning it upside down, and as seen from the front side, many pseudo trees are juxtaposed side by side in order. appear.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 (A) is a side view of a half-cut tree according to an embodiment of the present invention, FIG. 1 (B) is a rear view of a half-cut tree, and FIG. Rear view, FIG. 2
Is a front side perspective view of a half-cut tree, and FIG. 3 is a rear view of a half-cut tree according to another embodiment of the present invention.

First Embodiment A plastic half-cut tree 2 according to this embodiment shown in FIGS. 1 and 2 has a front part 4 having an uneven shape in which a plurality of timbers are juxtaposed and connected in a row when viewed from the front side. The first end 6 in the vertical direction is formed with an annual ring-like pattern resembling a cross section of a plurality of woods. Further, an annual ring-shaped pattern similar to that of the first end in the up-down direction is formed at the second end 8 in the up-down direction of the half-block tree 2.

A flat recess 5 is provided on the back of
The first connecting rod 10 and the second connecting rod 12 are integrally formed substantially parallel to each other along the horizontal direction. One of the first connecting rods 10 is formed in the flat recess 5 on the first end 6 side in the vertical direction, and the other second connecting rod 12 is formed on the second end 8 side in the vertical direction. It is.

Both ends 14, 16, 18, and 20 of the first connecting rod 10 and the second connecting rod 12 are formed so as to protrude outward from the side ends of the half-jointed tree 2, respectively.
The half cut tree 2 in which the first connecting rod 10 and the second connecting rod 12 are integrally formed on the back surface is obtained by injection molding using a plastic such as a recycled plastic.

In the present embodiment, the distance from the lower surface of the first connecting rod 10 to the first end 6 in the vertical direction of the half-connected tree 2 is (H1), and the distance from the lower surface of the second connecting rod 12 to the half-connected tree 2 is When the distance to the second end 8 in the vertical direction is (H2), H2 = H1 + α. Here, α is a size of a margin of 0 or more, preferably about 0 to 20 mm. If α is too large, the ends of the connecting rods 10 and 12 to be connected tend to be too far apart in the vertical direction when connecting the half-cut continuous trees 2 to each other, which tends to be difficult to connect.

In this embodiment, as shown in FIGS. 1 (B), 1 (C) and 2, when connecting the half-cut successive trees 2 in the horizontal direction, one half-cut successive tree 2 to be connected is connected. Are arranged upside down with respect to the upper and lower sides of the other half-cut tree 2 to be connected. As a result, the first connecting rods 10 and the second connecting rods 12 of the two half-cut trees 2 to be connected are arranged offset without interfering between adjacent half-cut pseudo trees, and these can be easily connected. it can. By repeating such connection, one kind of half-cut pseudo-tree 2 can be alternately arranged and connected while being turned upside down. When viewed from the front side, many pseudo-trees are arranged side by side in an orderly manner. Looks like.

Second Embodiment As shown in FIG. 3, a plastic half-cut tree 2a according to the present embodiment is a modified example of the half-cut tree 2 according to the first embodiment, and the shape on the front side is the same. And the structure on the back side is different.

That is, a half-cut tree 2a according to the present embodiment.
Here, the first connecting rod 10a and the second connecting rod 12a are integrally formed substantially parallel to each other in a substantially horizontal direction in a flat recess 5a formed on the back surface. First connecting rod 10
a is disposed in the flat recess 5a on the side of the first vertical end 6a of the half-cut pseudo wood 2a, and the second connecting rod 12a
Is arranged on the side of the second end 8a in the vertical direction of the half-cut dummy tree 2a. Both ends 14 of each connecting rod 10a and 12a
a, 16a, 18a, and 20a are formed so as to protrude to both sides from the side end of the half-block tree 2a.

In this embodiment, each connecting rod 10a, 1
The distance from the lower surface of one of the first ends 14a, 18a of the first half 2a to the first end 6a in the vertical direction of the half cut tree 2a is (H3, H
3 ′), and the distance from the upper surface of the other second end 16a, 20a to the first end 6a in the vertical direction of the half-block tree 2a is (H
4, H4 ′), H4 = H3 + α and H4
The rods 10a and 12a are set so that 4 ′ = H3 ′ + α.
Is formed in the middle of the process. In addition,
Α is a numerical range similar to that of the first embodiment.

Since H4 = H3 + α and H4 ′ = H3 ′ + α in the plastic half-cut tree 2a according to this embodiment, when these half-trees 2a are connected in the horizontal direction, one of the trees to be connected is connected. The upper and lower half-trees 2a are arranged without being reversed from the upper and lower sides of the other half-trees 2a to be connected. As a result, both ends of the connecting rods 10a and 12a to be connected to each other are arranged offset without interference between adjacent half-cut pseudo trees, and these can be easily connected. By repeating such connection, one kind of half-cut pseudo tree 2a can be arranged and connected without being turned upside down, and when viewed from the front side, many pseudo trees are arranged side by side in an orderly manner. Looks like.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the present invention.

For example, in the half cut continuous tree 2a according to the second embodiment, the connecting rod 10a or 12a that is discontinuous at the offset transition portion 30 may be formed without forming the offset transition portion 30.

Further, in the half cut trees 2, 2a according to the first and second embodiments, the connecting rods 10, 1
Both ends 14, 16, 18, 20, 14 of 2, 10a, 12a
The shapes of a, 16a, 18a, and 20a are simple short shapes having a connection hole 22 as shown in FIG. 4A, but are not limited to this, and notches as shown in FIG. It may be formed into a trapezoid having 24. In that case, the half-slice tree 2,2
a is effective when connecting each other not in the same plane but in a bent shape at a predetermined angle.

[0026]

As described above, according to the plastic half-cut tree according to the present invention, since the half-cut tree is made of plastic, it is lightweight and easy to handle. In addition, by using a single type of half-cut tree, simply connecting the connecting rods formed on the back, the half-tree can be easily connected to each other. Can be reduced.
